Within recent years certain combination materials have been developed which are very useful as electrodes, such as the combination of titanium metal with a very thin layer of platinum metal, which is in some cases as good as platinum used alone as an anode. In these composition materials the titanium serves as the current conductor for the microscopically thin layer of platinum. As long as this composition material is used with low current values, the voltage drop within the titanium conductor is in most cases acceptable, both from the point of view of loss in electrical energy as well as undesirable heat generation. The situation is different, however, in the case of current intensities of hundreds and thousands of amperes in a single electrode which are customary in the art. The electrical conductivity of titanium is about 30 times less than that of copper and the price of titanium is so many times more than the price of copper, that in order to achieve equal electrical conductivity values in titanium and copper, the cost of titanium would not only be several hundred times that of copper but the dimensions of the titanium work pieces would be such that they could not be used in practice solely from the technical point of view.
